SeCtion 6 – Concentration
The concentration measurement mode enables simple measurements of absorbance and concentration
to be performed. In this measurement mode it is possible to calibrate against a standard of a known
concentration or use a known factor. The sample is measured at one wavelength at one point in time.
There are no post measurement calculations available in this measurement mode.
6.1 MoDe SPeCiFiC PARAMeteRS
The concentration minimal operating menu enables
calibration to zero absorbance and simple readings to be
taken without changing any measurement parameters.
Pressing the key adjacent to the
JW icon opens the
expanded operating menu.
The concentration expanded operating menu enables
measurement parameters to be changed. The utility
toolbar on the left hand side of the screen enables access
to printing, print setup options, results, methods and
autologging options. For more details on the different
functions of the utility toolbar refer to section 10. The
settings icon enables the wavelength, units, resolution,
standard or factor to be set.

6.2.1 Selecting a Wavelength
The wavelength can be adjusted in the expanded
operating menu or in the settings menu. To adjust the
wavelength in the expanded operating menu use the
keys adjacent to the
arrow icons to increase or decrease
the wavelength.
